IMPROVEMENT 1N` MANuRE-FcRKs.

The Schedule referred to in these Letters Patent and making parl: of the same.

To all whom 'it-may concern Be it known that we, AMos S. BRI'NSER and HENRY BRIGKER, of Falmouth, in the county of Lancaster and Statev of' Pennsylvania, have invented a new and valuable Improvement in Mamme-Forks; and we do hereby declare that the following is a full, clear, and exact description `of the -'construction and operation' ofthe same, referenceheing had to the annexed drawing making a part of this specilication and to the letters and figures of reference marked thereon.

Figure 1 of the drawingis a plan view.

-Figure 2 is a-section.

Figure 3 is a View of the inside prong.

Our invention has relation 'to an improvement in the construction of manure -forks with separable prongs; and

It consists'in the construction and novel arrangement of the shouldered prongs and the open tubular ferrule, whereby the prongs and handle'maybe readily and rigidly secured in the ferrule, as hereinafter described.

The letter .A of t-he drawing designates the outer tapering tubular wall of myi'errule, which may be made oi' wrought-iron or of other suitable material.

B represents an inner tube, of similar metal, se-' cured within ,the ferrule Aat its smaller end and extending a certain distance toward the large end thereof. The outer vferrule-should be securely united to this inner tube by Welding.v v".Lhe opening through this innertube isrectangularinabreadth equal to the width of the tang of one of the prongs, and in width sufdcient to hold neatly the combined tangs of all the lW0nlS rJJhe smaller endl of the ferrule is cut away at each side of the rectangular perforation, through the walls of both tubes, forming rectangular notches az of the, width of the prongs. The ends of the ferrule which project on each side of thesenotches are rounded out to suit the curve between the central prongs.

This ferrule may be usedby suiting the thickness. of the tangs of the prongs thereto, for the attachmentA the central prongs, presently to be described.

The bases'of the prongs C C extend outward latl orally at right angles with-the direction of the handle ,through the notches z g, intvhich they rest, and which serve to assist in keepingthem steady and rm.

D D are the central prongs, whose tangs are withouthooks. These tangs are to be driven down between the outer prongs C 0and secured by a bolt or pin, e, passing in channels between them and through plete fer-rule. These central prongs are provided at their bases with the shoulders m m at right angles to Ola/im.

The combination of the `ferrules A and B, shanks c c and m m, and pin e, when constructed and arranged substantially as and for th purpose specified.

In testimony that we claun the above we have hereunto subscribed our names in the presence of two wit- DGSSGS.
